I think you just answered your own question right there lol. I don't think it's so much people are getting worse at basic grammar and spelling. I think it's partially because everyone is using cellphones,smartphones, iPhones, tablets, and what not that in the attempt to type messages real fast while on the go people basically butcher the English language. Not everyone I imagine uses a computer to look at the internet. Also Gary man I'm not making fun of you or anything/being snarky but I am pretty sure it is "incompetency". Also the OP wrote:

either, so finally the manger of the store was perplexed .... I'm not trying to knock
those who work at
a fast food restaurant,
because I worked
at one to pay my way through college
and at a convenience
store/gas station
as well. I just wanted to know when the bar
was lowered in our culture and
does anyone
have any other examples
/experiences of this? 
(The bold are mine: corrections/suggestions). So ya Scotty your message was clear enough but hey whose counting right? People use shorthand all the time. Then again some of us work all day and if your hurriedly working at your job, but want to share a profound thought people shouldn't really think much less of it; it's just the nature of the beast.
